Step 1

Blanch the green beans by boiling them for 2-3 minutes, then immediately transferring them to an ice water bath to stop the cooking. Drain and set aside.

Step 2

In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, garlic, salt and pepper until well combined.

Step 3

On a large serving platter or individual plates, arrange the mixed greens as a base. Add the cherry tomatoes, red onion, green beans, hard boiled eggs, potatoes, tuna, and capers (if using).

Step 4

Drizzle the dressing evenly over the salad just before serving.
